Abstract
Abstract A trigger safety lock for firearms consists of an attachment to the customary trigger guard. The trigger locking element is carried on a first component which has a guided sliding connection with a second component firmly attached to the trigger guard. Interengaging teeth on the first and second components secure the trigger locking element in an active or inactive position relative to the trigger, and yielding means maintain the teeth releasably engaged.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
101 words
A trigger safety locking attachment for firearms comprising a clamping element adapted to embrace fixedly a portion of a firearm trigger guard, a toothed bar pivotally connected with the clamping element and adapted to underlie a trigger guard closely, a trigger locking unit having guided sliding engagement with the toothed bar and having a resilient detent element releasably lockable with selected teeth on the bar for securing said unit in selected adjusted positions relative to a trigger, and a trigger engaging element on said unit movable therewith and relative to the trigger between forward trigger locking and rearward trigger releasing positions.
Claim 2
Dependent Claim
101 words
A trigger safety locking attachment for firearms comprising a clamping element adapted to embrace fixedly a portion of a firearm trigger guard, a toothed bar pivotally connected with the clamping element and adapted to underlie a trigger guard closely, a trigger locking unit having guided sliding engagement with the toothed bar and having a resilient detent element releasably lockable with selected teeth on the bar for securing said unit in selected adjusted positions relative to a trigger, and a trigger engaging element on said unit movable therewith and relative to the trigger between forward trigger locking and rearward trigger releasing positions.
Claim 3
Dependent Claim
36 words
The structure of claim 1, and said toothed bar having a longitudinal slot, and a lug on said unit engaging within the slot movably, the unit including a body portion closely and slidably underlying said bar.
Claim 4
Dependent Claim
40 words
The structure of claim 2, and a pair of rising laterally spaced arm extensions on the unit adapted to straddle a trigger guard, said trigger engaging element comprising a cross pin mounted on and extending between said rising arm extensions.
Claim 5
Dependent Claim
49 words
The structure of claim 1, and said resilient detent element comprising a single upturned tooth on said unit, a leaf spring on said unit carrying said tooth and urging it upwardly toward said toothed bar, the teeth of said bar downwardly facing for interlocking engagement with said upturned tooth.
Claim 6
Dependent Claim
40 words
The structure of claim 4, and side finger grip elements on the forward end portion of said leaf spring to aid in releasing said single tooth from the teeth of said bar and for shifting said trigger locking unit longitudinally.
Claim 7
Dependent Claim
38 words
The structure of claim 3, and an additional cross pin extending between said rising arm extensions and riding on top of the level portion of said trigger guard to support the rear end of the trigger locking unit.
Claim 8
Dependent Claim
83 words
The structure of claim 2, and said body portion of the trigger locking unit consisting of a one piece channel-like formation having a bottom wall and a pair of upturned side walls, said trigger engaging element comprising an abutment pin mounted on and extending between the side walls, and said resilient detent element comprising a leaf spring attached to the bottom wall of the body portion and having a forward end upturned tooth adapted to interlock with selected teeth of said toothed bar.
Claim 9
Dependent Claim
34 words
The structure of claim 1, and said clamping element comprising a two part clamp adapted to fit over trigger guards of varying thickness and a clamping screw securing said two parts in clamping relationship.
Claim 10
Dependent Claim
49 words
The structure of claim 1, and the pivotal connection between the toothed bar and clamping element comprising a forward upturned extension on the toothed bar, a hinge knuckle carried by the upturned extension, and a pivot pin engaging through said knuckle and through aligned openings in said clamping element.
Claim 11
Dependent Claim
43 words
The structure of claim 1, and said toothed bar and trigger locking unit being of generally eqUal length and lying close to the bottom of the trigger guard and being generally coextensive therewith lengthwise when said unit and toothed bar are relatively extended.
